Feldspar flotation as a quartz-purification method in

The presence of feldspar in sediment samples poses a challenge to the separation of quartz and affects the chemical procedures for extracting the radioactive CNs 10 Be and 26 Al. Additionally, feldspar contamination reduces the 26 Al/ 27 Al ratio, thus hinders the accurate determination of 26 Al by accelerator mass spectrometry (AMS).

Re-examination of common extraction and purification

quartz samples contained small amounts of feldspars (3– 10%), indicating that neither density separation nor mag-netic separation can fully remove all feldspars, and that HF etching is essential.
